Show me list of solar manufacturers which have restructured, left Australia or gone bankrupt over the past years.
In order to get follow up support for example regarding warranty for your solar panels and inverter it is important that you can contact the manufacturer or their representatives. If the manufacturer has left the industry, follow up service will be more difficult to obtain.
Rest in Peace: The List of Deceased Solar Companies
The sad, inevitable results of the Venture Capital bubble and solar shakeout
By Eric Wesoff: December, 2014
We listed the more than 200 VC-funded solar startups back in 2008. We knew that we'd be writing about most of them on their way up -- as well as on their way down. Add one more solar company to the list of insolvent solar firms. It's one you may not have heard of: Concentrator Optics. The firm had received investment from Capricorn Venture Partners to build Fresnel lenses for the CPV market.
Capacity coming offline means less-efficient companies closing down. Of course there's another long list of relatively unknown Chinese companies closing down as well.
Keeping track of failing solar companies in 2011 and 2012 bordered on full-time work. That was when solar manufacturing overcapacity and price pressure brutally culled the field. The 2014 dead pool is much smaller and much less painful to view.
This is an updated list of solar companies that have closed, gone bankrupt, become insolvent, ended up in assignment for benefit of creditors, or have been acquired in less than positive circumstances. Although there is a macabre element to this list, it's actually positive news for the industry. The solar companies left standing in 2015 are the firms with effective business plans and value to add to the marketplace. The survivors made it through the bottleneck of the early 21st century solar market.
Here's the updated list of the solar firms that have fought the good fight but have moved on.
